Finding the far right online: an exploratory study of white supremacist websites

White supremacists and the Far Right political movement in the UK have, had considerable success in spreading their messages through Web sites. Some of these Web sites clearly contribute to an enabling environment for racially motivated violence in our towns and cities and possibly help to underpin also the rise of, and support for, the Far Right in the UK and elsewhere in Europe. From a position that acknowledges the enduring issue of white hegemony in Western societies, this paper provides a number of research-based recommendations for further research and future policy and practice in tackling white supremacist racial hatred on the Net

Arts and cultural organisations: organisational perspectives on youth outreach work (pre-covid) in disadvantaged neighbourhoods – a case study of Thanet

Research has shown that engagement with arts and culture is beneficial to young people from disadvantaged backgrounds (Arts Council England, 2020). The sector is widely acknowledged for the role it plays in tackling wider social issues and Arts Council England claims that it will increase opportunities for young people to experience creativity (Arts Council England, 2020). Set against this background, this research study has been developed to explore the role of youth outreach activities/events, from an organisational perspective of arts and cultural organisations, using the case study area of Thanet. Thanet is a coastal area located in East Kent, with rates of unemployment, crime and deprivation that exceeds the national average (Thanet District Council, 2018). To address the research aim, the methodology was designed to, firstly, provide a comprehensive audit of arts and cultural organisations in Thanet that engage with youth outreach activities/events with youths 11-18 years. This allowed the study to explore the nature of these organisations and the scope of outreach work carried out within Thanet. The audit conducted via web-based secondary analysis and an online survey also provided the basis for organisations to be sampled for a set of ten semi-structured interviews. These interviews carried out online due to the Covid-19 pandemic, allowed the study to explore the enabling environment, positive mental health, and challenges/barriers faced when planning/organising youth outreach that targets the target demographic. The research demonstrates organisations perspectives on the role of youth outreach, while examining the challenges/barriers arts and cultural organisations in Thanet are experiencing due to funding cuts, increased competition, and low staffing. This research outlines successful ways of running youth outreach through key elements such as partnerships, funding, and technology. Further research would need to be conducted to ensure representativeness of this study’s findings in similar areas of deprivation i.e. Dover, Blackpool, Hastings, and Ilfracombe

Equilibrium radiative heating tables for Earth entry

The recent resurgence of interest in blunt-body atmospheric entry for applications such as aeroassisted orbital transfer and planetary return has engendered a corresponding revival of interest in radiative heating. Radiative heating may be of importance in these blunt-body flows because of the highly energetic shock layer around the blunt nose. Sutton developed an inviscid, stagnation point, radiation coupled flow field code for investigating blunt-body atmospheric entry. The method has been compared with ground-based and flight data, and reasonable agreement has been found. To provide information for entry body studies in support of lunar and Mars return scenarios of interest in the 1970's, the code was exercised over a matrix of Earth entry conditions. Recently, this matrix was extended slightly to reflect entry vehicle designs of current interest. Complete results are presented

Diasporic Literary Archives Network and the Commonwealth: Namibia, Nigeria, Trinidad & Tobago, and other examples

This article brings together three themes: primary sources for the study of literature; the diasporic nature of literary manuscripts; and the impact of the diaspora on the English-speaking world, in general, and the Commonwealth, in particular. The article begins by describing some general characteristics of literary manuscripts, focusing in particular on their diasporic nature. It then outlines the work of the project known as the Diasporic Literary Archives Network in the years 2012-15. It concludes with an assessment of the archival diaspora as it affects cultural and literary heritage work in Commonwealth countries

On the Γ\Gamma-limit for a non-uniformly bounded sequence of two phase metric functionals

In this study we consider the $\Gamma$-limit of a highly oscillatory Riemannian metric length functional as its period tends to 0. The metric coefficient takes values in either $\{1,\infty\}$ or $\{1,\beta \varepsilon^{-p}\}$ where $\beta,\varepsilon > 0$ and $p \in (0,\infty)$. We find that for a large class of metrics, in particular those metrics whose surface of discontinuity forms a differentiable manifold, the $\Gamma$-limit exists, as in the uniformly bounded case. However, when one attempts to determine the $\Gamma$-limit for the corresponding boundary value problem, the existence of the $\Gamma$-limit depends on the value of $p$. Specifically, we show that the power $p=1$ is critical in that the $\Gamma$-limit exists for $p < 1$, whereas it ceases to exist for $p \geq 1$. The results here have applications in both nonlinear optics and the effective description of a Hamiltonian particle in a discontinuous potential.Comment: 31 pages, 1 figure. Submitte

Plants for predators - a participatory experiment

Encouraging natural enemies by growing attractant plants is a highly effective method of pest control in organic systems. However, it is important to establish which plants are most effective at attracting benefi cial insects. Experiments were carried out by 179 HDRA members, who grew four plant species (Coriander, Corn Marigold, Fennel and Phacelia) in their gardens and allotments. Over the course of the growing season, assessments were made on the growth and flowering of the plants and the presence of four key groups of beneficial insect (ladybirds, hoverflies, lacewings and parasitic wasps). Phacelia established quickly and its long flowering period meant it attracted insects throughout the summer. However, Phacelia was only the most attractive plant at the end of the season and insects preferred the other trial plants when they were in flower. Results highlight the importance of growing a range of flowering plants to provide resources for beneficials throughout their activity period

Deep Ordinal Reinforcement Learning

Reinforcement learning usually makes use of numerical rewards, which have nice properties but also come with drawbacks and difficulties. Using rewards on an ordinal scale (ordinal rewards) is an alternative to numerical rewards that has received more attention in recent years. In this paper, a general approach to adapting reinforcement learning problems to the use of ordinal rewards is presented and motivated. We show how to convert common reinforcement learning algorithms to an ordinal variation by the example of Q-learning and introduce Ordinal Deep Q-Networks, which adapt deep reinforcement learning to ordinal rewards. Additionally, we run evaluations on problems provided by the OpenAI Gym framework, showing that our ordinal variants exhibit a performance that is comparable to the numerical variations for a number of problems. We also give first evidence that our ordinal variant is able to produce better results for problems with less engineered and simpler-to-design reward signals.Comment: replaced figures for better visibility, added github repository, more details about source of experimental results, updated target value calculation for standard and ordinal Deep Q-Networ

Use of capillary electrophoresis as a method development tool for classical gel electrophoresis

Capillary electrophoresis (CE) was used to optimize the buffer pH, ionic strength and sulfated cyclodextrin concentrations for enantiomeric separation of piperoxan. These enantioseparation conditions were then applied to a classical gel electrophoresis system. Binding constants of the sulfated beta-cyclodextrin–piperoxan couple were approximated using CE and the effects of organic solvents on the system were also investigated

On the Interpretation of the broad-band millimeter-wave flux from Orion

Spectral observations of the core of Orion A at wavelengths around 1.3 mm show a high density of strong, broad emission lines. The combined flux in lines with peak antenna temperatures stronger than 0.2 K accounts for approximately 40 percent of the broad-band millimeter-wave flux from the region. Thus the broad-band flux from Orion A is in large part due to sources other than dust emission
